PURPOSE OF REVIEW To review the evidence that the Alzheimer peptide β-amyloid interacts with the blood coagulation system and influences the pathophysiology of the disease. RECENT FINDINGS β-amyloid can interact with fibrinogen and blood coagulation factor XII and trigger ischemia and inflammation. SUMMARY β-amyloid interacts with fibrinogen and factor XII. These interactions can lead to in...
We fractionated frontal cortical grey matter from human Alzheimer's disease and control subjects into four biochemically defined pools that represent four distinct compartments: soluble/cytosolic, peripheral membrane/vesicular cargo, integral lipid/membranous pools and aggregated/insoluble debris. Most of the readily extractable amyloid-β remains associated with a lipid/membranous compartment. ...
The amyloid-β peptide is considered as a key player in the development and progression of Alzheimer's disease (AD). Although good evidence exists that amyloid-β accumulates inside cells, intracellular brain amyloid-binding proteins remain poorly characterized. Proteomic profiling of rat brain homogenates, performed in this study, resulted in identification of 89 individual intracellular amyloid...
BACKGROUND AND PURPOSE We and others have shown that soluble amyloid β-peptide (Aβ) and cerebral amyloid angiopathy (CAA) cause significant cerebrovascular dysfunction in mutant amyloid precursor protein (APP) mice, and that these deficits are greater in aged APP mice having CAA compared with young APP mice lacking CAA. Amyloid β-peptide in young APP mice also increases infarction after focal c...
Alzheimer's disease is the most common form of dementia, with amyloid protein assembly associated with the pathogenesis of disease. Thus it is of utmost importance to reveal the detailed structure of the amyloid protein aggregates. In article 1500369, F. Besenbacher, M. Dong and co-workers discover a new parallel-like β-strand molecular monolayer structure of amyloid peptide at hydrophobic inte...
Insertion of an anthranilic acid in an amyloidogenic peptide sequence generates a novel conformationally restricted α/β-hybrid peptide that inhibits amyloid formation of Aβ(1-40) and disrupts preformed fibrillar aggregates in vitro. Such β-sheet breaker hybrid peptides (BSBHps) may be useful for designing novel physiologically important compounds relevant to diverse amyloidoses and for studying...
The amyloid protein aggregation associated with diseases such as Alzheimer's, Parkinson's and type II diabetes (among many others) features a bewildering variety of β-sheet-rich structures in transition from native proteins to ordered oligomers and fibres. The variation in the amino-acid sequences of the β-structures presents a challenge to developing a model system of β-sheets for the study of...
